INSY 3303 Exam 2 Review Study Guide
with Complete Solutions

Access Layer - Answer✔✔-The layer that provides network access.




Ex. Local Area Network (LAN)


ACK (acknowledgement message) - Answer✔✔-the part of the ARQ algorithm that lets the sender know

that the package has been correctly received without errors.


Address Resolution - Answer✔✔-the process of translating the application layer address (or server

name) of the destination into a network layer address, and in turn translate that into a data link layer

address


Server Name Resolution - Answer✔✔-translation of application layer addresses into network layer

addresses and is done using the Domain Name Service (DNS) (Ex. Website URL to IP address)


ARP (Address Resolution Protocol) - Answer✔✔-A core protocol in the TCP/IP suite that belongs in the

Network layer of the OSI model. ARP obtains the MAC (physical) address of a host, or node, and then

creates a local database that maps the MAC address to the host's IP (logical) address.


ARQ (Automatic Repeat reQuest) - Answer✔✔-when a receiver that detects an error simply asks the

sender to retransmit the message until it is received without error.

Asychronous Transmission - Answer✔✔-often referred to as start-stop transmission because the

transmitting computer can transmit a character whenever it is convenient, and the receiving computer

will accept that character.


Baselining - Answer✔✔-when designers must review the list of applications that will use the network

and identify the location of each, and the information is added to the emerging network documentation.


BGP (Border Gateway Protocol) - Answer✔✔-a dynamic distance vector exterior routing protocol used

on the Internet to exchange routing information between autonomous systems—that is, large sections

of the Internet.


What are the disadvantages to using BGP? - Answer✔✔-It is large, complex, and often hard to

administer.


Backbone Network (BN) - Answer✔✔-A large network to which many networks within an organization

are connected. It usually is a network that interconnects all networks on a single site.


Bottleneck - Answer✔✔-a circuit that is filled almost to its capacity and is the critical point that

determines whether users get good or bad response times.


Building-Block Network Design Process - Answer✔✔-when networks that use a few standard

components throughout the network are cheaper in the long run than networks that use a variety of

different components on different parts of the network.


What is the goal of the Building-Block Network Design Process? - Answer✔✔-a simpler design process

and a more easily managed network built with a smaller range of components.
